Sorry to here about your issues, and i wouldnt put much faith in the breeder as well since she is putting this situation off. About the muzle thing if he bit you hard enough to draw blood id say try it to be on the safe side id hate for him to get your daughter as badly, but im not by far the most experienced to offer advise on this issue. But if ya check out a Rott familiar trainer or behavurist and decide ya cant keep him and your breeder wont take him back (wich the few breeders ive dealt with begged for me to bring them back if i decided they wouldnt work out, I mainly have had all rescues and 1 pet store bought dog at witch im getting basted on the breeding forrums for

) id look into Rott/rescue. Placing him there and finding another with better temperment (definately not from the same beeder). Again look into a more experienced person than me about this breed and muzle maybe out of the question.
Good Luck on whatever you decide
